OK, looks like we have the right family from Czernowitz. Here is the record for Stepan:
Farbatiuk Stepán, Inft., IR. Nr, 24, Bukowina, Zastawna, . Jurkoutz, 1893; verw., kriegsgef., Kombiniertes Evakuations- spital Nr. 27 in Wladimir,"Rußland
He was from Bukowina in the Zastawna district in the town of Jurkoutz which I believe is now called Czernowitz.
Notice that Stepan was wounded and had been a prisoner of war.
